Abstract
3-Methyltriazolothiazole (2) and 3-phenyltriazolothiazole (3) were regiospecifically lithiated at position 6, triazolothiazole (1) at position 6 and 3 with the former predominating. The lithiated triazolothiazoles (4),(10) and (11) reacted with a number of electrophiles to give x: 6- disubstituted triazolothiazoles, which could be converted into 2, 4-disubstituted thiazoles.
